Much like last weekend, we have cold air and moisture joining together to bring some snow to parts of Western Washington, while the rest of the region will just be soaked with a typical rain.

The most likely spots for snow are in Whatcom County, the San Juan Islands and along the Hood Canal area.

A wet snow or mix of snow and rain have been falling across parts of the region today and moisture will increase overnight and into Sunday as a warm front approaches, but warm air will also quickly be eroding snow chances.

A Winter Weather Advisory is in effect for the Whatcom County and San Juan Island areas from Saturday night through Sunday morning for up to 2 inches of snow Saturday night and then another 1-2 inches or so are possible during the day Sunday.

The Advisory is also in effect for the higher hills of the Hood Canal area -- this is towns along US 101 on the eastern slopes of the Olympics like Brinnon, Seabeck, Hoodsport and down to Shelton. 1-2 inches of snow is likely Saturday evening through Sunday.

The Eastside Foothills and a few other areas near the regions in the watch may see a little snow, but no significant accumulations are expected (maybe 1" in the foothills), and the main Seattle area will likely remain too warm for snow and just get rain.

Just like last weekend, arctic air has settled into the interior of British Columbia and is pushing through the Fraser River Valley, blowing out into Whatcom County and spreading south.

A weak trough of low pressure will continue to spread some light flurries or snow/rain showers around Saturday night -- showers of snow mainly relegated to mainly Whatcom/Skagit/San Juan Island areas and the Cascade foothills.

Elsewhere we'll see a few light snow/rain/mix showers as we've seen in a few spots already, but no big deal, just for show. Lows will be around 30 in Bellingham and low 40s around Seattle.

Moisture increases a little Saturday night as a warm front approaches. The areas in the Advisory could see 1-2 inches overnight. Areas near the watch like Skagit, Island and Clallam Counties could see a slushy inch overnight, as could the Cascade foothills. Snohomish County, especially the areas around 500 feet, could see a dusting to 1/2" or just a non-stick snow. The rest of the region, including Seattle-Bellevue proper, will likely just see light rain showers.

The bulk of the warm front arrives around midday Sunday, bring a decent batch of moisture into the region. This will be rain for most everyone, exception being those close to the Fraser River Outflow -- essentially the northern areas near the Canadian border that got snow last weekend -- could see a period of moderate snow Sunday until enough warm air moves in to change to rain. Total snow accumulations could reach 1-3 inches by Sunday night with perhaps some isolated spots that could go a little higher if the cold air is stubborn.

Long range forecasts suggest the rest of the week will be mild and occasionally wet.
